Product info of JUN-505 (TR-525), blood purification machine

Some users reported that pushing the key lock button of JUN-505 (TR-525), blood purification machine dimly illuminated the red LED indicating pump stop, when the pump was in operation.

The result of the investigation revealed that this may occur due to a slight time lag between individual storage elements in the timing of communication, even though the elements meet the specifications. The elements control the illumination of the LED, which flashes repeatedly with a very high frequency. This illumination system mainly used for indoor indicators is controlled by the dynamic illumination system.

Due to such difference in the timing, it depends on individual differences whether the LED is lighted or not and how bright it is at a given moment.

Note that this phenomenon is only related to LED illumination control and does NOT affect the functions of the products.
